I'm running an ancient Norfrost Ice Chef C105 (from the 1980s). It works fine, but I'm trying to figure out how much it's costing me in electricity. It has no manual, and there are no specs online for it (that I could find). It says on the metal plate on the back:
Watts 150 Amps 1 2 Charge R12 Volume gross 108 l Volume net 102l Freezing capacity 4 kg per 24 hours
So, taking the 150 wattage figure, I get ( 150 * 24 * 365 ) / 1000 = 1314 kWh per year. Which, at 13p per kWh, is £171.
But a modern equivalent freezer has a spec of 163 kWh per year (£21).
But does a freezer run at the full wattage continuously? Or does it switch on and off based on the temperature inside? And can the wattage it draws vary? Basically, how can I improve my calculation, because I think the 1314 kWh figure is way off!
[The freezer itself is completely reliable, never broken down or had a problem in 30+ years.... just the energy cost is worrying me]
